Gaussian mixture model entropy coding

The present invention relates to a method for decoding an encoded signal, the method comprising the steps of: receiving at least one code stream comprising an entropy-encoded signal, the signal being entropy-encoded with one or more Gaussian mixture models (GMMs), and the at least one code stream comprising: information for acquiring parameters of the one or more GMMs; acquiring the GMM parameter according to the information from the at least one code stream; and entropy decoding the signal by using the GMM with the acquired GMM parameter. The invention also relates to a corresponding encoding method, a decoder and an encoder. 本发明涉及一种对编码信号进行解码的方法，所述方法包括以下步骤：接收包括熵编码信号的至少一个码流，所述信号用一个或多个高斯混合模型(Gaussian mixture model，GMM)进行熵编码，并且所述至少一个码流包括：用于获取所述一个或多个GMM的参数的信息；根据来自所述至少一个码流的所述信息获取所述GMM参数；使用具有所述获取的GMM参数的GMM对信号进行熵解码。本发明还涉及一种相应的编码方法、解码器和编码器。
